    摘要： This invention relates to extruders of the type which employ single screws that use chaotic mixing to generate substantially better distributive mixing. Such structures of this type, generally, stretch and fold material lines repeatedly such that interfacial areas between material elements increase exponentially and heat/mass transfers are greatly enhanced.

    摘要： A plasticating apparatus and method for its use including a rotating screw having a helical flight disposed within and cooperating with the inner wall of a heated barrel with said barrel provided with inlet and outlet openings so that particles of resinous material are introduced through said inlet opening to a helical valley extending along said flight to be plasticated by said screw and advanced towards said outlet opening. A barrier extends along said helical valley to divide said helical valley into coextensive side by side helical valley sections. The barrier extends in a path which is non-parallel and alternating with respect to the helical flight so that the pitch of the barrier is alternately greater than and less than the pitch of the helical flight. The height of the barrier is less than the height of the flight so that the resinous material overflows the barrier due to changes in width of said side by side helical valley sections.

    摘要： Fittings for reducing cracking in soap bars including protrusions on the end flight on the worm or auger of a soap plodder to break up the glazed layer of soap formed by the wiping action of the end flight on the soap as it is discharged. The plodder is provided with a cone nozzle and fittings are provided for eliminating the spiral movement of the soap mass and forming a laminated bar by extrusion through aligned slots. The concept of the invention also includes the elimination of the central or the spongy mass of soap and the formation of a harder grain structure for the soap.

    摘要： A double-screw extruder for thermoplastic materials, with a first and a second extruder screw, whereby the extruder screws have an inlet and an outlet and a core, helically extending screw flights being arranged through the core from the inlet to the outlet, so that the screw peaks and valleys are circumferential, and the peaks of the first screw penetrate into the valleys of the second screw, and vice versa. The screw flights may have a geometry which is step-shaped in cross section, whereby the steps may be provided such that the stepped course of the peaks is congruent with the stepped course of the valleys.

    摘要： Screw press, preferably for removing liquid from a material to be conveyed, comprising a screw shaft (1) complete with a helical conveying flight (2) mounted on the screw shaft (1) and a housing shell (3) surrounding it, where a transport channel (4) is formed for the material to be conveyed between the screw shaft (1), the conveying flight (2), and the housing shell (3). In order to prevent conveyed material components from adhering to the screw shaft (1), and thus uneven filling of the transport channel (4), the invention provides for the screw shaft (1) to have a surface profile (5), at least in one section of the transport channel (4).

    摘要： A plasticating apparatus including a rotating screw having a helical flight disposed within and cooperating with the inner wall of a heated barrel. Resinous material is introduced to a helical valley extending along said flight to be plasticated by said screw and advanced towards an outlet opening. The screw has a metering section for working said resinous material at high temperature. The bottom surface of the helical valley in said metering section is divided into side by side relatively shallow and relatively deep levels having a depth differential therebetween. The relatively shallow and relatively deep levels extend along the bottom surface of the helical valley in side by side helical paths. The side by side helical paths have a different pitch than the pitch of the helical flight so that the helical flight periodically interrupts the helical paths. The depth of the shallow level remains substantially uniform in the metering section and the depth of the deep level also remains substantially uniform in the metering section. The depth differential between the shallow and deep levels is bridged by a descending-ascending shoulder without any intervening barrier flight. During operation, the level differential induces a continuous tumbling and mixing action upon the molten resin in the mixing section.
